Cutoff
ProLink III Device Tools > Configuration > Process Measurement > Flow > Volume Flow Cutoff
Field Communicator Configure > Manual Setup > Measurements > Flow > Volume Flow Cutoff
Volume Flow Cutoff specifies the lowest volume flow rate that will be reported as measured. All volume flow
rates below this cutoff are reported as 0.
Procedure
Set Volume Flow Cutoff to the value you want to use.
• Default: 0.0 l/sec (liters per second)
• Range: 0 l/sec to x l/sec, where x is the sensor’s flow calibration factor, in units of l/sec, multiplied by 0.2
Interaction between Volume Flow Cutoff and mAO Cutoff
Volume Flow Cutoff defines the lowest liquid volume flow value that the transmitter will report as measured.
mAO Cutoff defines the lowest flow rate that will be reported via the mA Output. If mA Output Process
Variable is set to Volume Flow Rate, the volume flow rate reported via the mA Output is controlled by the
higher of the two cutoff values.
Volume Flow Cutoff affects both the volume flow values reported via the outputs and the volume flow values
used in other transmitter behavior (e.g., events defined on the volume flow).
mAO Cutoff affects only flow values reported via the mA Output.
Cutoff interaction with mAO Cutoff lower than Volume Flow Cutoff
Configuration:
• mA Output Process Variable: Volume Flow Rate
• Frequency Output Process Variable: Volume Flow Rate
• AO Cutoff: 10 l/sec
• Volume Flow Cutoff: 15 l/sec
Result: If the volume flow rate drops below 15 l/sec, volume flow will be reported as 0, and 0 will be used in all
internal processing.
Cutoff interaction with mAO Cutoff higher than Volume Flow Cutoff
Configuration:
• mA Output Process Variable: Volume Flow Rate
• Frequency Output Process Variable: Volume Flow Rate
• AO Cutoff: 15 l/sec
